On 17 August 2017, the Russian cosmonauts Fyodor Yurchikhin and Sergey Ryazansky will deploy five nanosats during EVA. Among them are three „students“ satellites commemorating the 60the anniversary of the Sputnik launch and the beginning of Space Age.

The Tomsk-TPU-120 CubeSat is built by the Tomsk Polytechnic Institute in concert with Energia Corporation (part of ROSCOSMOS State Corporation) and the Institute of Strength Physics and Materials Science, Siberian Department of RAS. This is the first Russian nanosat which casing is made using 3-D technology. The satellite will be in orbit about a year and half downlinking telemetry and voice messages. The data from the satellite may be received at the 437.025MHz amateur frequency. As part of the Radioskaf space experiment, the constellation of Tanyusha-YuZGU with call sign RS6S and Tanyusha-YuZGU-2 with call sign RS7S small spacecraft will be deployed.

The Tanyusha project is implemented by the Energia Corporation jointly with South-West State University (Kursk).Several experiments on the constellation satellite interaction with each other, data transmission and vacuum density measurement using the YUZGU-developed vacuum gauge will be conducted in space. In honor of the 60the anniversary of the Sputnik launch and the 160th anniversary of the birth of Konstantin Tsiolkovsky, the Tanyusha satellites will transmit a voice greeting in Russian, English, Spanish and Chinese. The greeting may be received at the 437.05 MHz amateur frequency.

Moreover, the TNS-0 No.2 nanosat will be launched. The satellite is based on the unified platform which is designed for nano class spacecraft and developed by JSC „Russian Space Systems’ (part of the ROSCOSMOS State Corporation) for Rocket and Space Corporation Energia.

During the satellite operation in orbit, the key services systems, sensors, computer system and experimental navigation system will be tested. The data collected will be used to upgrade the platform when manufacturing future vehicles to operate in the Earth’s orbit and deep space. TNS-0 No.2 is scheduled for operation for the period of three-five months. The satellite will be controlled by the RKS MCC. The Sfera satellite to be deployed by the Russian cosmonauts on 17 August is built by R&S Corporation Energia. It is an all-metal sphere. Such a shape is convenient because the atmospheric braking of satellite does not depend on its attitude control in space.

The Sfera motion after launch will be determined using ground measuring facilities. As part of the Vektor-T experiment on board ISS RS the data on its movement will be used to specify the atmospheric model parameters and to verify the algorithms used for atmospheric density calculation and spacecraft motion in low near-earth orbit prediction. The satellite will be in orbit for several months.
